Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an office processing apparatus such as an image forming apparatus, and more particularly to an office processing apparatus for a physically handicapped person (person with a physical disability) who works on a wheelchair.

[0002]

2. Description of the Related Art Conventionally, in OA equipment such as copiers and printers, the appropriate height of a workbench is set to, for example, 900 mm to 1000 mm above the ground from the viewpoint of operability for healthy people. That is, it is designed so that a person with a height of about 150 cm or more can easily set a document and operate various keys in a standing position.

[0003]

However, in the office processing apparatus such as the image forming apparatus as described above, there are special restrictions such as people who use wheelchairs to carry out their daily lives due to illness or injury of their limbs. The height of the operator who has it is very poor. That is, aside from desk-top type personal devices, the type of machine that is installed on the floor of the office and used jointly has a height that considers only the operability of healthy people, so it is suitable for operators with physical restrictions. The operation was very difficult.

[0004] Therefore, conventionally, the lower base of the device is adapted to the handicapped person so that the handicapped person can escape from the foot of the handicapped person in a wheelchair to improve the usability. A hollow is provided.

However, since the upper part of the recess becomes the table of the lift table and moves up and down, the table of the lift table rises, and when it is in the upper position, the knees of the operator of the recess may enter. It became possible, and if the elevator was lowered as it was, there was a problem that the knees would be caught in the descending table and it would be dangerous.

The present invention has been made in view of the above problems, and is excellent in operability not only for healthy people but also for physically handicapped persons, and it is certain that the operator's knees or the like are caught in the lifting table. The purpose is to provide a safe and secure office processing device.

[0007]

An office processing apparatus according to the present invention comprises an elevating device for elevating and lowering an apparatus main body, and a detecting means for detecting it when an external object is contacted during an elevating operation of the apparatus main body. And a control means for controlling the lifting device based on the detection output of the detection means.

The detecting means is composed of a pressure-sensitive sensor for detecting pressure and a detecting member for increasing and transmitting the pressure due to contact with the object to the pressure-sensitive sensor.

Further, the control means is adapted to stop the raising / lowering operation of the apparatus main body when the detection means detects the contact with the object.

[0010]

According to the present invention, when the operator's knee or the like comes into contact with the apparatus main body during the elevating operation, a signal is output from the detecting means to the control means. The control means controls the lifting device by the signal, and stops the lifting operation of the device body, for example.

Next, a case where a person with a disability in a wheelchair operates the copying machine having the above structure will be described. Here, it is assumed that the height of the operation panel 2 is raised or lowered in three steps of 1100 mm, 950 mm, and 800 mm by the elevating device 14 as shown in FIG.

FIG. 3 shows a height (950 mm) adapted to a healthy person.
The state is set to. As described above, the apparatus main body 1 can be raised by pushing the raising switch 9 on the raising / lowering operation panel 8 and lowered by pushing the lowering switch 11. When the operator in the wheelchair pushes the lowering switch 11 so as to be easily operated, the lifting device 14 starts the lowering operation, and the slide volume 1 shown in FIG.
When 5 detects 800 mm (body height suitable for an operator in a wheelchair), the lifting device 14 stops. At this height, as shown in FIG. 4, a normal copy operation becomes very easy.

Next, a case where a trouble such as a paper jam occurs in the apparatus body 1 will be described. As mentioned above, JA
In the M processing operation, the operability is better when the height of the apparatus main body 1 is increased to about 1100 mm. Then, when the raising switch 9 is pushed, the raising / lowering device 14 starts the raising operation, and stops when the slide volume 15 detects the height of 1100 mm. By raising the apparatus body 1, the operator on the wheelchair can easily perform the JAM processing as shown in FIG.

Next, the safety function of the present invention will be described. The elevator device 14 and the apparatus main body 1 of the copying machine according to the present embodiment are equipped with a safety function in order to prevent a danger associated with the elevator operation by the elevator device 14. That is, the above-mentioned pressure sensitive portion 16 is provided on the lower side of the device body 1, and when the operator's limbs or the like are sandwiched between the device body 1 and another object (especially for raising and lowering for JAM processing). (This often occurs when the table is raised and then lowered), and the pressure sensing unit 16 detects the pressure and transmits the detection signal to the CPU 6. Then, the CPU 6 issues an instruction for a safe stop operation, assuming that a dangerous situation has occurred. At this time, in this embodiment, the raising / lowering operation is stopped and stopped on the spot, but it is also possible to perform an operation such as stopping after returning a minute distance to prevent overstroke. .

Here, as shown in FIGS. 2 and 6, the pressure-sensitive portion 16 includes the pressure-sensitive sensor 101 and the pressure-increasing arm 10.
Each of the arm portions 102a to 102e of the pressure boosting arm 102 is provided with a protrusion 105.
The pressure-sensitive sensor 101 includes the arm portions 102a to 102a.
Since pressure due to contact with an object is received through the protrusion 105 of 102e, pressure detection accuracy is high, and it is possible to reliably prevent a part of the operator's body from being caught in the lifting table.
It is highly safe.

That is, when there is no pressure increasing arm as shown in FIG. 7, when the knee 108 as a part of the human body pushes the pressure sensitive sensor 101 in the direction of arrow A, the pressure is dispersed and the feeling is particularly high. If the sensitivity of the pressure sensor 101 is low, the knee 108 is pressed before the pressure is detected, causing pain.

However, as shown in FIG. 6 of this embodiment, when the pressure increasing arm 102 is provided between the knee 108 and the pressure sensitive sensor 101, the contact surface 10 of each of the arm portions 102a to 102e.
Since the pressure received by 6 is concentratedly amplified by the projection 105 and transmitted to the pressure sensor 101, even if the knee 108 is pressed with the same force, the depressions 109a, 10a of the pressure sensor 101 are formed.
9b is large, an object can be detected with a small force in the direction of arrow A, and the knee 108 or the like does not feel pain.

As described above, since the elevating device 14 is provided, the operability is excellent not only for the healthy person but also for the physically handicapped person, and the pressure sensitive portion 16 is provided on the elevating table on the upper part of the elevating table so that the knee or the like of the physically handicapped person is Since the emergency stop function is provided to immediately detect that the operator is caught and stop the lifting operation, it is possible to reliably prevent the operator's knee or the like from being caught in the lifting table.

In the pressure-increasing arm 102 of the pressure-sensitive portion 16 shown in FIG. 2, the arm portions 102a to 102e are made of elastic members made of, for example, PP (polypropylene) molding resin or the like, and the operator's knees or the like. When a pressure is applied by the contact of the object, the object is deformed (moved) in that direction. And each arm part 102a-102
The arm body 103 from which e is projected is fixed to the bottom surface of the bottom plate 107 of the apparatus body 1, and the surface 104 of the pressure-sensitive sensor 101 is also in contact with the bottom plate 107.

Further, a stopper 110 is provided between the arm portions 102a to 102e and the bottom plate 107 in order to prevent an abnormal pressure from being applied to the pressure sensitive sensor 101. Since the stopper 110 is provided, even if the pressure is increased by the pressure increasing arm 102, the pressure sensitive sensor 1
01 will not be overburdened.
