The control device 10 includes an image-forming-apparatus controller 11 that controls the operation of the image forming apparatus 1, a controller portion 12 that prepares image data in accordance with a printing request, a power supply 13, and so forth.
The image forming unit 2 is provided at the bottom thereof with the sheet feeding device 20 in which plural sheets P as recording media are stacked. The sheets P whose position in the width direction is determined by a regulating plate (not illustrated) are picked up one by one from the top of the stack by a sheet pickup member 22 toward the left side (in the −X direction). The sheet P thus picked up is transported to a nip part between a pair of registration rollers 23.
The photoconductor units 30 are arranged side by side above the sheet feeding device 20 (in the Z direction) and include respective photoconductor drums 31 as image carriers that are driven to rotate. The developing devices 40 form toner images in colors of yellow (Y), magenta (M), cyan (C), and black (K) on the photoconductor drums 31, respectively.
The toner images in the different colors formed on the photoconductor drums 31 of the photoconductor units 30 are sequentially electrostatically transferred to an intermediate transfer belt 51 of the transfer device 50 (in first transfer), whereby the toner images are superposed one on top of another. The toner images superposed on the intermediate transfer belt 51 are collectively transferred by a second transfer roller 52 to the sheet P fed from the pair of registration rollers 23 and guided to the second transfer roller 52 by a transport guide (not illustrated).
The sheet P to which the toner images have been collectively transferred by the transfer device 50 is transported to the fixing device 60 by a transport guide (not illustrated) with the toner images unfixed. The unfixed toner images are fixed under pressure and heat applied thereto by a combination of a fixing roller 61 and a pressing roller 62.
The sheet P having the fixed toner images is guided to the pair of first discharge rollers 63 or the pair of second discharge rollers 64 by a transport guide (not illustrated) and is discharged by the pair of first discharge rollers 63 or the pair of second discharge rollers 64 onto a sheet output tray T1 or T2 provided in the inner sheet-output space S.
Referring to
(2.1) Inner Sheet-Output Space
The inner sheet-output space S of the image forming apparatus 1 is defined by the reading-unit-supporting portion 4 and an exterior member 6 on one lateral side thereof, the sheet output tray T1 of the image forming unit 2 on the lower side thereof, the bottom portion 3a of the reading unit 3 on the upper side thereof, and a rear panel 101 on the rear side thereof, with the front side thereof being open to the operator. The reading-unit-supporting portion 4 is a pillar portion that supports the reading unit 3. The exterior member 6 covers a sheet discharge portion, where the pair of first discharge rollers 63 and the pair of second discharge rollers 64 are exposed to the outside of the image forming unit 2.
(2.2) Speaker
The exterior member 5 that is provided on the operator side of the reading-unit-supporting portion 4 is a holed member having holes that are open to the inner sheet-output space S.
The exterior member 5 covers a pillar 100 included in the reading-unit-supporting portion 4 and has plural sound releasing holes 5a each extending from the inner side through to the outer side of the exterior member 5. The sound releasing holes 5a allow an alarm sound that is output from the speaker 7 to pass therethrough. The speaker 7 is fixed to the pillar 100 behind the exterior member 5. Desirably, the sound releasing holes 5a are provided at an opening ratio of 50% or higher with respect to the caliber of the speaker 7.
As illustrated in
The speaker 7 is a small-caliber speaker unit and includes, for example, a diaphragm 7a having a radius of about 20 mm. The speaker 7 is controlled by the control device 10. The sound generated from the back of the diaphragm 7a provides the operator notifications of errors or job completion, audio operation guides, and so forth.
Exemplary error notifications include notifications of, a jam or misfeed of a document in a document feeder of the reading unit 3, a jam or misfeed of a sheet P in the sheet feeding device 20, a breakdown of hardware included in the image forming unit 2 or the control device 10, and so forth.
The image forming apparatus 1 according to the first exemplary embodiment includes the speaker 7 that provides the operator with notifications of errors or job completion, audio operation guides, and so forth. The speaker 7 is provided on the operator side of the body of the image forming apparatus 1 and faces toward the inner sheet-output space S.
Therefore, the alarm sound that is output from the speaker 7 is released toward the operator side while the alarm sound is made to echo on the exterior member 6, the sheet output tray T1, the bottom portion 3a of the reading unit 3, the rear panel 101, and so forth that define the inner sheet-output space S. Thus, the alarm sound is assuredly delivered to the operator while the reduction in the sound pressure is suppressed.
The speaker 7 is concealed from the outside by the exterior member 5 having the plural sound releasing holes 5a that are open to the inner sheet-output space S, and is fixed to the pillar 100 behind the exterior member 5.
Therefore, the speaker 7 and the sound releasing holes 5a are less visible from the outside of the image forming apparatus 1, and favorable appearance is provided.
(2.3) Attaching Finishing Sheet-Processing Device
As illustrated in
The finishing sheet-processing device 70 is set on the upper surface of the sheet output tray T1 in the inner sheet-output space S. In this state, a gap G is provided between a sheet receiving surface 71 of the finishing sheet-processing device 70 and the reading-unit-supporting portion 4 (see
Hence, the alarm sound that is output from the speaker 7 provided on the operator side of the reading-unit-supporting portion 4 and facing toward the inner sheet-output space S is reflected by the sheet receiving surface 71 of the finishing sheet-processing device 70 and is released from the gap G toward the operator side, thereby being assuredly delivered to the operator.
The position of a speaker 7 in an image forming apparatus 1A according to a second exemplary embodiment of the present invention will now be described with reference to
As illustrated in
The image forming apparatus 1A includes a supporting portion 102 fixed to the reading unit 3 and projecting from the reading unit 3 toward the operator side. The operation information portion 80 according to the second exemplary embodiment is detachably supported at the top of the supporting portion 102.
The bottom face of the supporting portion 102 has plural sound releasing holes 102a each extending from the inner side through to the outer side of the supporting portion 102. The sound releasing holes 102a allow the alarm sound that is output from the speaker 7 provided behind the supporting portion 102 to be released downward into the inner sheet-output space S.
The alarm sound thus output from the bottom of the supporting portion 102 is reflected by the sheet output tray T1 defining the lower side of the inner sheet-output space S and is released toward the operator side. Thus, the alarm sound is assuredly delivered to the operator.
The plural sound releasing holes 102a provided in the bottom face of the supporting portion 102 that supports the operation information portion 80 face down toward the inner sheet-output space S and are therefore less visible from the operator side. Thus, favorable appearance is provided.
As illustrated in
The first exemplary embodiment and the second exemplary embodiment each concern a case where the image forming apparatus 1 or 1A includes the speaker 7 as a sound generating unit. Alternatively, the sound generating unit may be a buzzer that provides notifications of errors, job completion, and so forth.
