Abstract

PURPOSE:To copy even an image drawn on a wall surface, etc., together with an ordinary original by moving a copying machine body along columns fixed on a base. CONSTITUTION:The copying machine body is supported by the columns 2 and 3 and slides up and down on the columns 2 and 3. Then when the image drawn on the wall surface 7 is copied, a wall surface copy mode is set and a reflector 131 and the 1st mirror 132 are set. Then, a pinion is driven to set the lowermost position of the image on the wall surface 7 at the position of an exposure window 14. Then, the copying machine body is elevated in a direction D and a copying process is started. Thus, the optional image drawn on the wall surface 7 is copied. When a normal copy is taken, a normal copy mode is set and the reflector 131 and mirror 132 are set. In this state, an original inserted into an original insertion tray 110 is conveyed inward and a copying process is carried out. Consequently, the original image is scanned at a point P in a figure and the same copying operation with a normal copying machine is performed.

Description

[Detailed Description of the Invention] Technical Field> The present invention relates to a novel copying device capable of copying images outside the copying device main body, such as images drawn on walls, in addition to originals set in the copying device main body. .

<Prior Art and Its Disadvantages> Conventional copying machines only have the function of copying originals set in the main body of the copying machine, and cannot directly copy images written on blackboards or walls. Why (・Some devices that read the image drawn on the board with a CCD sensor, process it digitally, and print it are also in practical use, but they are extremely expensive and are not only integrated with the board.) Because of this, it was not possible to copy images drawn on arbitrary blackboards or walls.

<Object of the Invention> The object of the invention is to enable the main body of the copying machine to move along a support fixed to the stand, so that the main body of the copying machine can be moved along with a normal original
It is an object of the present invention to provide a device capable of copying images drawn on a work board, wall surface, etc.

<Configuration and Effects of the Invention> The present invention includes a support fixed to a stand and a copying device main body slidably attached to the support, and the optical path of the optical system in the copying device main body is connected to the copying device. The present invention is characterized in that means is provided for switching between a first optical path for exposing an original set in the main body and a second optical path for exposing an image placed outside the copying apparatus main body along the support.

With this configuration, according to the present invention, if the optical path of the optical system in the copying device main body is switched to the second optical path and the copying device main body is slid on the support and fixed at an arbitrary position, the It is possible to copy an image placed along a support, that is, an image drawn on a wall or the like. Furthermore, by switching the optical path of the optical system to the first optical path, it is possible to copy a document placed in the main body of the copying apparatus in the same manner as in a normal copying apparatus.

<Embodiment> FIG. 1 shows a schematic diagram of a copying apparatus which is an embodiment of the present invention. The copying apparatus main body 1 is similar to a normal copying apparatus,
Copying process section including photoreceptor drum etc., optical system,
Equipped with paper feed power, etc. This copying machine main body 1 is 2
It is supported by two columns 2.3 and can be slid up and down on the columns. A rack 20.30 is formed inside the column 2.3, and the copying apparatus main body 1 is provided with a pinion that engages with this rack 20.30. As will be described later, this pinion is rotated by driving the motor within the copying machine main body 1, thereby moving the copying machine main body 1 downward. The column 2.3 is fixed to the platform 4. This table 4 is equipped with four stoppers and rolling bodies 40 at its bottom. A stopper button 41 provided on the upper part of the table 4 operates or releases the stopper of the rotating body 40 with a stopper. Stopper button 4
If 1 is pressed, the switch 1 operates and the rotating body 40 becomes unable to rotate. That is, the stand 4 is fixed. When the stopper button 41 is pressed again, the stopper operation is canceled and the rotating body 40 can rotate freely. In other words, the stand 4 can be moved freely.

On the sides of the pillars 2 and 3, there is a scale 5 indicating the height from the bottom surface.
is written. Furthermore, an operating section 6 is provided below the support column 3. This operation section 6 includes a display 60. Print key 61. Up key 62. Down key 63. Numeric keypad 64. It is composed of movement keys 65. The display 60 displays the number of copies and the like.

The print I key 61 instructs a copy operation. The lift key 62 instructs the copying apparatus main body 1 to rise. Down key 63
supports the lowering of the copying apparatus main body 1.

The numeric keypad 64 is used to set the number of copies and the vertical movement distance of the copying apparatus main body 1. The movement key 65 moves the copy scanning main body 1
instructs the user to move by a distance set using the numeric keypad 64.

FIG. 2 shows the relationship between the ranks provided on the supports 2 and 3 and the pinion provided within the main body 1 of the copying apparatus. A total of four pinions 10 to 13 are provided within the main body 1 of the copying apparatus. Each pinion is connected to a motor in the main body 1 of the copying apparatus, and can be rotated in the direction of arrow A or arrow B by a clutch mechanism (not shown). Further, the rotation of each pinion 10 to 13 is controlled by a pulse encoder attached to the rotation shaft of the motor so that the rotation angle and rotation speed of each pinion can be accurately detected. When the pinions 10 to 13 rotate in the direction of the arrow A, the copying apparatus main body 1 moves in the direction D (upward). When the pinions 10 to 13 rotate and shift in the B direction, the copying apparatus main body 1 moves in the C direction (downward). A brake mechanism is attached to each pinion 10 to 13, and this brake mechanism operates when the copying apparatus main body 1 moves to a predetermined height.

By operating the brake mechanism, the copying apparatus main body 1 is stopped at that height.

FIG. 3 shows a schematic structural diagram of the main body 1 of the copying apparatus.

A photosensitive drum 100 is arranged approximately in the center of the main body l of the copying apparatus. This photosensitive drum 1 ().

Around the lsL charger 1o1. Developing unit 102. 'Transfer charger 103. Static elimination deasher 10
4. The IJ-Ning Uniso I-105 cutters are provided in this order. Photoreceptor 1'' ram 100 rotates in the direction of arrow E.

A document insertion tray 110 is located on the left side of the copying machine main body 1.
is placed horizontally. Insert this original 1-ray 110
The original inserted from the original frr, which includes the feed and IL roller 111, is fed through the l viewing path 112, and is ejected to the original output tray 113. An original inserted from the original insertion tray 110 is exposed to light at a point P in the figure by an optical system to be described later.

A paper feed case I-1 is located below the document insertion tray 110.
20 is mounted horizontally. This paper feeding power cent 120
From there, one sheet of paper is fed by a paper feed roller 121. The fed paper is sent to the transfer section via the paper transport path 122, and the toner image formed on the photoreceptor drum 100 is transferred by the transfer charger 103. The ♀IL for use after transfer is not adsorbed by the suction Uniso I-123 and is then sent 11Q, the toner image on the paper is fixed by the fixing roller 124, and the paper is ejected to the paper ejection tray 125.The optical system is a light source 130. ．． Reflector 131, first mirror 132. It is composed of a lens 133 and a second mirror 134. The reflector 131 and the first mirror 132 can be rotated by 90 degrees as shown by solid lines and dotted lines in the figure. When a wall copy mode, which will be described later, is set, the reflector 131 and the first mirror 132 are set at the solid line position in the figure. When a normal copy mode, which will be described later, is set, the reflector 131 and first mirror 132 are centered at the dotted line position in the figure. When the reflector 131 and the first mirror 132 are centered at the solid line position in the figure, the light source 130
The light irradiated from the wall surface 7 exposes the Q point on the wall surface 7 through the exposure window 14 of the copying apparatus main body 1 which is opened facing the wall surface 7. The reflected light from point Q is reflected by first mirror 132 and reaches the surface of photoreceptor drum 100 via lens 133 and second mirror 134 . In this state, when the copying apparatus main body 1 rises at a constant speed in the D direction, the image drawn on the wall surface 7 is copied. When the reflector 131 and the first mirror 132 are centered at the dotted line position in the figure, the light source 1
The light from 30 reaches point P. The reflected light from point P is reflected by the first mirror 132 and reaches the surface of the photosensitive drum 1.00 via the lens 133 and the second mirror 134.

In this state, when a document is inserted from the document insertion tray 110 and conveyed through the first general feeding path 112, the document is scanned at point P, and the document image is copied.

When attempting to copy an image drawn on a wall in the above configuration, the wall copy mode is set and the reflector 131 and first mirror 132 are set at the positions indicated by the solid lines. Next, the pinions 1o to 13 are driven in the A direction or the B direction so that the lowest position of the image on the wall surface 7 comes to the exposure window 14. Thereafter, the copying apparatus main body 1 is raised in the direction D and the copying process is started. Of course, the copying apparatus main body 1 is raised by driving the pinions 10 to 13. By such an operation, any image written on the wall surface 7 can be copied. When normal copying is to be performed, the normal copying mode is set and the reflector 131 and first mirror 132 are set to the dotted line positions in the figure. In this state, the document insertion tray 110
The original inserted into the machine is transported inside and the copying process is executed.

As a result, the original image is scanned at point P in the figure, and copying can be performed in the same manner as in a normal copying apparatus.

FIGS. 4(A) to 4(C) are flowchart 1 showing the general operation of the copying apparatus. In this embodiment, the entire copying apparatus is controlled by a cPU (not shown). The flowchart shown in FIG. 4 shows the operation of this CPU, and the procedure is stored in advance in the ROM.

When the power is turned on, predetermined initialization processing such as clearing the RAM work area is performed in step nl (hereinafter step ni is simply referred to as n+), and further, the fixing roller 124 is heated to perform warm-up processing. At n2, it waits for the copying operation to become possible (ready state), and when the ready state is reached, it waits for the flag PF to be set at n3.

This flag PF is set when the print key 61 is pressed. When the print key 61 is pressed, the flag P
When F is set, the process moves to a copy cycle at n4. In this copy cycle, the copying apparatus main body 1 rises at a constant speed in the D direction when in the wall copy mode. In addition, in the normal copy mode, the paper feed roller 111 is driven to feed a document from the document insertion tray 10 and generally feed it inside through the first general feed path 112 .

The reflector 131 and the first mirror 132 are controlled by key interrupt processing, which will be described later.

Therefore, in the copy cycle n4, the image on the wall is copied in the wall copy mode, and the original set on the original insertion tray 110 is copied in the normal copy mode. At n5, the copied counter C is incremented. Then, at n6, the flag PF is reset, and at nl, it is determined whether the contents of the copy completed counter C and the contents of the set number of copies counter are equal. If they are equal, the process returns to n3; otherwise, the process returns to n4 and the copy cycle is executed again.

Through this operation, copy cycles are executed until C=K.

When any key on the operation unit 6 is pressed, the screen shown in FIG. 4(B)
Proceed to the key interrupt processing shown in . nl.

Next, determine the type of key that was pressed. If it is a numeric keypad, the process advances to n12 and the entered numeric value is set in the counter K via the buffer. If the print key 61 is directly pressed without pressing the rear side of the numeric keypad, the contents of the counter remain unchanged as the set number of sheets counter.

If the key interrupt cause is the * key, the process advances to n14 and the state of flag F1 is determined. Flag F1 indicates how many times the * key has been pressed. When the button is pressed for the first time (first time), F1=0.

If it is the second time, it is Fl-1. At first flag F1
Since is in the reset I state, the process advances to n15.

At n15, the value pressed before the * key is set in the start counter STC. Next, flag F1 is set and the motor is turned on at n17. Although not shown in detail, if the contents of the start counter STC are at a higher position than the current exposure window position, the clutch that connects the motor and pinions 10 to 13 is connected in the forward direction, and the copying machine main body 1 is moved in the D direction. ”I raise it twice. Further, when the position indicated by the start counter STC is lower than the position of the exposure window 14, the clutch is connected in the opposite direction and the copying apparatus main body 1 is lowered in the C direction. In n18, the position of the exposure window 14 is the start counter S.
It is determined whether the position matches the position indicated by TC. This determination is made by first determining the difference between the position indicated by the STC and the position of the exposure window 14, and checking whether there is rotation of the pinions 10 to 13 corresponding to this difference. As described above, since the rotary encoder is attached to the rotating shaft of the motor, the rotational state of the pinions 10 to 13 can be detected based on the output of the rotary encoder. When the main body 1 of the copying apparatus is moved until the exposure window 14 coincides with the position indicated by the start counter STC, the counter (2) is reset at n19 and the process returns.

When the second * key is pressed, the data placed before the second * key is set in the end counter EDC at n20. The content of the end counter EDC is the distance that the copying apparatus main body 1 moves after the copying process. Although not shown, the content of this end counter EDC is referred to in the copy cycle n4, and is used as the moving length of the copying apparatus main body 1, that is, the scanning distance of the image on the wall surface. Next, reset the flag F1 at n21 and return it to the original state at n1
Proceed to step 9.

When the key interrupt factor is the movement key R, the contents of the counter ■ ( are transferred to the start counter STC and senor 1 in n31, and in n32 and n33, the copying machine body 1. Clear the counter K at n34 and return.

If the key interrupt factor is the up key 62 or the down key 63, n35. In step n36, each step is raised or lowered by one step.

If the cause of the key interrupt is the print key 61, print 1 to flag PF are set in n38. When this flag PF is set, the process moves to the n4 copy cycle shown in FIG. 4(A).

When the key interrupt cause is the mode key, the mode flag MF is inverted at n40. When the mode flag MF is reset, it becomes the normal copy mode and the reflector 131
The first mirror 132 is then set at the position indicated by the dotted line in FIG. When the mode flag MF is in the cent state, the wall copying mode is set, and the reflector 131 and first mirror 132 are set at the actual positions shown in FIG. As described above, the state of this mode flag MF is determined in the copy cycle of n4, and when MF=O, the original inserted from the original insertion l-ray 110 is scanned. When MF=1, the copying machine main body 1 is moved at a constant speed in the D direction (
Upper stomach) and scan the image on the wall surface.

With the above operations, the scales 11 on the wall are copied as well as normal copying.
Any image written on W can be easily copied.

In this embodiment, the main body of the copying apparatus is shown in which the optical system is fixed, but the image on the wall may be scanned by moving the optical system. In this case, the portion facing the wall of the main body of the copying apparatus is constructed of a glass plate, and the light source section is configured to be movable in the vertical direction as in a normal optical system movable copying machine.
