An object of the present invention is to provide a unit type thermal label printer which is separable into functional elements. It is another object to produce a thermal label printer which can be dynamically adapted for use at different places and times, and in different configurations.
The present invention attains this object by providing a unit type thermal label printer formed of separable thermal label printer elements, a label printer unit, a data terminal unit, an applicator unit, and a handle unit. These units are freely electrically and mechanically connectable.
The present invention provides a modular unit type thermal label printer which is comprised of a label printer unit for thermal character printing and a data terminal unit. The data terminal unit is electrically and mechanically attachable with, and detachable from, the label printer unit. An applicator unit is mechanically connectable to the label printer unit for the application of adhesive backed labels. A handle unit is mechically detachable from and connectable to the label printer unit that is used for hand held operation.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIG. 1, the thermal label printer 1 comprises a main or label printer unit 2, data terminal unit 3, applicator unit 4, and handle unit 5. There are accessories comprising a pen scanner 6 and touch scanner 7 for reading data. Cable 8 is used for connecting label printer unit 2 to data terminal unit 3. Data input to data terminal unit 3 is performed by scanning optically readable data with pen scanner 6 or by touching the data with touch scanner 7.
As shown in FIG. 3, label strip T includes backing sheet S which is coated with a separating agent. A plurality of labels L, are each coated with an adhesive, detachably adhered continuously along the length of label strip T. On the labels L of the thermal label strip T, there is printed information I in the form of bar code B which may represent information such as a merchandise or manufacturing code, a department code or a price. Backing sheet S is provided with holes D which are used for strip T position detection purposes. The holes D can also be utilized for conveyance purposes by engagement with conveyor roller 19 (FIG. 2).
The internal structure of printer 1 along with printer unit 2, data terminal unit 3, applicator unit 4, and handle unit 5, all assembled will now be described with reference to FIG. 2.
The thermal label strip T passes from thermal label roll R on support member 10 into label strip passage 18 via guide rollers 17 of an upper press member 16.
Thermal label strip T passes via conveyor roller 19 and position sensor 15 to thermal print head 20 and platen 21. The strip T is redirected at platen 21 around bending pin P where labels L are peeled off. Therefore, just the backing strip S is directed back for engagement with conveyor roller 19, guided by guide rollers 23 of lower press member 22. The backing sheet S is fed out from data terminal unit 3 via discharge outlet 14a.
Conveyor roller 19 is driven by the stepped rotation action of stepping motor M so as to move the thermal label strip T in the required direction for printing and conveyance.
Data terminal unit 2 houses control circuit 26, which is connected to battery 27, interface 28, ROM program memory 29, RAM data memory 30, and keyboard 3a which includes a power switch. The interface 28 is used for data input from and output to external devices not shown while ROM 29 is used to store communication and control programs. Display 3b, socket 3c which is used for scanners 6 and 7, print switch 3d, and printer unit 2 are also connected by interface 3e and controlled by control circuit 26.
The interface 3e is connected to interface 2a of printer unit 2 via socket 3c for linking printer unit 2 to data terminal unit 3. The sensor 15, thermal print head 20, stepping motor M and print switch 2c are connected to an auxiliary control circuit 2b which is connected to interface 2a.
The control circuit 26 controls data input/output operations and general control or overhead functions. Auxillary control circuit 2b controls printing and label conveyance for printing. The battery 27 is preferably a rechargeable type and can be connected, via socket 13, to an external battery charger (not shown).
FIG. 4 shows thermal label printer 1 connected to a microcomputer 32 so as to allow data I/O operations therebetween. Data can be transferred to or received from microcomputer 32 via socket 12 and cable 33. An acoustic coupler may also be used to link the printer 1 to host a computer via telephone by a wired or wireless link (not illustrated). Data input/output operations can be carried out by radio with the provision of an antenna 3f on data terminal 3, and as indicated in phantom in FIG. 1.
The applicator unit 4 is provided with bending pin P and application roller 38, and can be mechanically attached to and detached from printer unit 2 by means of an engaging projection 4a. The printer unit 2 is provided with a pair of engaging pins 40 on the side facing the data terminal unit 3. An engaging member 41 is pivotably attached to the upper front edge of data terminal unit 3, and by use of spring 42, can be engaged with and disengaged from, an engaging portion provided on the printer unit 2. The top of handle unit 5 is provided with a dovetail portion 43 which can be engaged with and disengaged from a dovetail groove 44 provided on the lower part of printer unit 2. The handle unit 5 is lockable into place by lock 45. It is to be understood that the mechanical connections of various units are not restricted to those shown in the drawings but rather components can be adapted as desired to form a configuration that is in line with individual or specialized requirements.
FIGS. 5 to 7 show some of the formats that can be accomplished by combining units 2, 3, 4, and 5, scanners 6 and 7, and cable 8. FIG. 5 shows an example of the data terminal unit 3 connected to label printer 2 for desk-top type applications. There, the thermal label strip T only engages with conveyor roller 19 at the top portion thereof. Labels L are therefore fed out of the front of the printer unit 2, together with backing sheet S so that the labels L can be peeled by hand and applied to an object.
With the type of application shown in FIGS. 6 and 7, labels are printed by operating switch 2c (shown in FIG. 2). For the configuration shown in FIG. 5, switch 3d (shown in FIG. 2) is used to print labels.
Thus, through the use of printer 1, various units can be combined together so that data input/output and printing of labels for different applications can be done. Therefore when printing labels of different sizes, different printer units corresponding to different sizes of desired labels may be chosen. This gives printer 1 a wide range of applicability. Additionally, there are also service and maintenance benefits, since only the broken unit needs to be replaced.
Some of the potential applications for the present thermal printer include labelling and reordering of merchandise and inventory control at retail outlets, management of business data files, printing of blood data cards and sample tube labels at blood banks, printing of bar code labels for patient charts and medical certificates at hospitals and clinics, process, parts and inventory control in factories, printing of freight confirmation labels at parcel reception/dispatch points, management of customer data, and data and printing of labels relating to outside suppliers at department stores and supermarkets.
The thermal label printer according to this invention is therefore not limited to data input/output functions. By providing great flexibility in the printing of labels, the thermal label printer is applicable to a great many fields, and offers better economic efficiency.
Although the present invention has been described in connection with a preferred embodiment thereof, many other variations and modifications will now become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited not by the specific disclosure herein, but only by the appended claims.
