Abstract

PURPOSE:To make the best use of read-out information and to improve operability by providing a control means which releases a waiting mode when the insertion of a copy mode specifying paper into a reading means is detected while a copying machine main body is in the waiting mode. CONSTITUTION:A reader control circuit 48 for a reader is connected to a CPU 40 through a serial interface 47. In addition to an insertion inhibition display and an insertion permission display, a carrying motor 49 carrying the copy mode specifying paper and a read sensor 50 optically reading a mark entered on the paper are connected to the reader control circuit 48. In the case the copy mode specifying paper is inserted into the reading means in spite of the waiting mode, the waiting mode is released. Consequently, read-out mode information is always used efficiently, and the mode suitable for the information is set to take a copy without releasing the waiting mode through a key.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a copying apparatus capable of specifying a copy mode using a copy mode specification sheet.

2. Description of the Related Art In recent years, as copying apparatuses have become multifunctional, the number of keys and switches related to copy mode settings has increased, making operations more complex, and it is possible that a desired copy may not be obtained due to an operational error or the like. This is particularly inconvenient when the copy requester and the copy operator are different. For this reason, the copy requester writes copy mode selection information, such as information on the number of copies, on a copy mode specification sheet, and the copy operator inserts this sheet into an optical reader and reads it. A copying machine has been proposed that automatically sets a copy mode according to information and enables copying.

For example, according to Japanese Unexamined Patent Publication No. 53-131048, an information card with the number of copies programmed is set on an automatic document feeder (ADP) like a document, and the information on the information card is read when the document is transported in the same way as the document. , it is described that the mode should be set so that the number of copies is achieved. However, such a copying machine has an information reading means provided inside the copying machine, which increases the overall cost of the copying machine. In particular, for users who do not need to set the copy mode using an information card and think that manually setting the normal keys on the operation panel is sufficient, even though such an information reading means is unnecessary, the built-in There is also the problem that it cannot be removed.

In this regard, for example, as shown in Japanese Patent Application Laid-Open No. 56-143455, if the information reading device is not built into the copying machine body but is an option separate from the copying machine body, only the necessary users can input the card. We will be able to provide a method.

Problems to be Solved by the Invention Incidentally, in a copying machine, all or part of the display on the operation section is turned off, such as the timer OFF mode and the preheating mode in which AC power system loads such as the fixing heater are kept energized. There is a mode. In such a mode, although there is a difference in whether the fuser heater is energized or not, the function of the copying machine itself is basically stopped in either mode, and the actual If you want to copy, the mode cannot be set as is, so you need to perform a mode release operation. Such a mode will be referred to as a standby mode in this specification.

Here, as mentioned above, the information reading means, which is separate from the main body of the copying machine, detects when the copy mode designated paper is inserted into the insertion slot, drives the paper conveyance motor, and reads the information on the paper. During the transport, the mode designation information written on the paper is read.

However, when the copying machine is in standby mode, even if the information on the mode specification sheet is read by the information reading means, the copying machine itself, which is supposed to receive the information, is not equipped to receive the information. Therefore, the mode information read by the information reading means is wasted. Therefore,
The information on the paper must be read again after the standby mode cancellation operation is performed, resulting in poor operability.

Means for Solving the Problem A copy mode specification form for specifying a copy mode according to a prescribed format, a reading means for reading the copy mode specified by the copy mode specification form, and a copying method according to the copy mode read by the reading means. The copying apparatus has a copying mode setting means for setting a mode, and the copying apparatus is provided with a control means for canceling the standby mode when insertion of the copying mode designated sheet into the reading means is detected during the standby mode of the copying machine main body.

Even in operation standby mode, if a copy mode designated paper is inserted into the reading means, the standby state will be canceled, so the read mode information will not be wasted, and the standby mode can be activated by pressing the key. The mode is set according to the information and copying is possible without a mode cancellation operation.

Example An embodiment of the present invention will be described based on the drawings.

First, FIG. 2 shows the overall external configuration, in which a copying machine main body 4 is provided, which has first and second paper feed trays 1 and 2, and further has a third paper feed tray 3 that can be additionally connected as an option. There is. Furthermore, an ADF 5 is mounted on the top of the copying machine main body 4 to automatically transport a document (not shown). 6 is an operation section, and 7 is a paper output tray.

A reading device 8 serving as reading means for reading information on a copy mode designation sheet (described later) is attached to a part of the upper part of the copying machine main body 4.

This reading device 8 is formed with an insertion slot 9 into which a copy mode specified paper is inserted, and when a paper sensor detects that a paper is inserted into the insertion slot 9, an internal transport motor is driven to transport the paper. It is conveyed inside by rollers (not shown), and information (marks) written on this copy mode designation sheet is read by an optical reading sensor. After reading, the conveyance motor is reversed and the conveyance roller discharges the paper from the insertion slot 9 again. The reading device 8 transmits the reading mark information to the control system within the copying machine main body 4. Furthermore, an insertion prohibition indicator 10 and an insertion permission indicator 11 are provided on the upper surface of the reading device 8.

The on/off status of these indicators TO and 11 is controlled by signals from the copying machine main body 4, and when the insertion prohibition indicator 10 is lit, the transport motor will not operate even if paper is inserted into the insertion slot 9. It does not rotate and paper is not conveyed. Furthermore, these indicators 10 and 11 are never turned on or off at the same time.

Next, FIG. 3 shows the configuration of various keys, switches, and displays in the operation section 6. First, the key switches include the start key 12, numeric keypad 13, clear/stop key 14, interrupt key 15, stack key 16, sort key 17, mode clear key 18, preheat key 19,

, an enter key 33, a program key 34, a timer set key 35, etc. are provided. Some of these keys have mode display LEDs that indicate the mode depending on the key operation.
36 (shown in black) is provided. Also,
A fixed pattern display section 37 using liquid crystal is provided to display paper size, number of copies, abnormality display, etc. moreover,
A liquid crystal full-dot display section 38 is also provided for displaying the mode when setting the mode mainly by key operation.

Furthermore, the block diagram configuration of the control system is shown in FIG.

First, the main control circuit of the copying machine main body 4 is the CPU 40, R
It consists of a microcomputer system consisting of OM41 and RAM42. Here, the RAM 42 that stores control flags and data is backed up by a battery 43, and even if the power of the copying machine is turned off, the RAM 42
The contents are stored in non-volatile memory so that they do not disappear. R
A program is written in the OM 41, and processing is performed according to this program. Further, a programmable clock 44 IC is connected to the CPU 40, and is configured to turn on or off the AC power source of the copying machine and various displays on the operation section 6 at predetermined times.

200 Serial interface 45 for PU40
An operating section control circuit 46 for the operating section 6 is connected through the. This operation unit control circuit 46 includes various keys (for example, the start key 12, etc.) shown in FIG.
D36, fixed pattern display section 37 and full dot display section 38 are connected, and serial interface 45
It is possible to import operation key data into the CPU 40 via the CPU 40 or to control the display state.

Further, a reading device control circuit 48 for the reading device 8 is connected to the CPU 40 via a serial interface 47. In addition to the above-mentioned insertion prohibited indicator 10 and insertable indicator 11, the reader control circuit 48 includes a transport motor 49 that conveys the copy mode designation paper, and a reader that optically reads marks written on the copy mode designation paper. A sensor 50 is connected. This makes it possible to read mark data on copy mode designated paper.

Next, copy mode designation paper 51 used in this embodiment
is shown in Figure 5. This copy mode designation sheet 51 can designate the main mode among various copy modes in a mark sheet format according to a predetermined format, and specifically includes a number of copies designation section 52, a copy size designation section 53, It consists of a copy magnification specifying section 54, a double-sided copy specifying section 55, a sorter mode specifying section 56, a program specifying section 57, and a preliminary specifying section 58. The black portion 59 at the right end is address information. In each designation area, by writing a dot mark or a - mark in the white square of the place you want to designate, the reading device 8 detects this mark and sends it to the copying machine main body. It is something. Areas where nothing is entered or mode portions are ignored and set to standard mode. Furthermore, if a mode that cannot be incorporated, for example, a sort mode and a stack mode, is specified at the same time, it is determined that a reading error has occurred, and the copy mode specification sheet 51 is ejected from the insertion slot 9, invalidating the read data. Make it.

Here, a preliminary designation section 58 shown surrounded by a broken line is a designation section that is not limited to specific mode designations, and mode designations specific to various copying machines can be assigned to this section. When a mark is designated somewhere in this preliminary designation section 58, the reading device 8 simply transmits only a signal indicating the designated position to the copying machine main body 4 side. Therefore, which position in this preliminary designation section 58 corresponds to which mode is determined for each copying machine. The mode designation by this preliminary designation section 58 is used for modes not included in the specific mode for this paper, such as special magnification mode designation, color copy designation, and the like. An explanation will be added regarding this preliminary designation section 58. Generally, the copy mode designation sheet 51 and reading device 8 as in this embodiment are
It can be used not only with one model of copying machine but also with different models of copying machines (of course, on the copying machine main body 4 side, the hardware configuration as shown in FIG. 4, that is, the interface and (It is necessary to prepare the software configuration.) Under these circumstances, various types of copying machines have common functions, such as enlarging and reducing, and special functions that are provided only to certain models. Therefore, on the copy mode specification sheet 51, as for the number of copies and modes such as double-sided copying that are common to each model, these modes are printed in advance to make them common, as shown in FIG. The preliminary designation unit 58 is used to select a mode based on a special function that is lacking. For this reason,
Since the preliminary designation section 58 is not common to all models,
The mode name is not printed and is made known to the user in the user manual of each model of copier.

In other words, even if marks are written at the same location in the preliminary designation section 58, their meanings, ie, designation modes, will differ depending on the type of copying machine used. In a copying machine model that does not have functions other than the common function, this preliminary designation section 58 has no meaning, so even if something is read by the reading device 8, it is ignored.

Here, the signals transmitted from the reading device 8 to the copying machine main body 4 will be explained. The data length is bits bO-b7, 8
The lower 4 bits (bO to b3) are address information for identifying data, and the upper 4 bits are marked data. Specifically, for the number of copies, the x1 column shown in FIG. 5 is the first data for the number of copies,
The O column represents the 10th place data, and the X100 column represents the 100th place data. The copy size is B5-A3, each bit B.
4 to b7. Copy magnification, double-sided copy mode, sort mode, and program mode also correspond to bits. The program modes 1 to 5 mean the memory numbers that store the mode set by the program mode, and when one of these is specified, the mode stored in that memory is set. . these,
When shown in a table, it looks like Table 1. As the control data, a handshake signal is used in which the input cloth is FFI (and the end of data is OPH). Also, the logic of each bit is "1", which means that it is active and marked. , Reserve-1 to Reserve-3 for the reserve designation section 58 indicate marked locations.

Also, the signals transmitted from the copying machine main body 4 side to the reading device 8 will be explained. This also has a data length of 8 bits,
The lower 4 bits are an address for identifying data, and the upper 4 bits are data.

All of these are control data and are allocated as shown in Table 2. Note that whether or not the input of the copy mode designation paper (sheet) is allowed/disabled is data such that FO is allowed, and OOH is data that is not allowed.

Based on the control data shown in Tables 1 and 2, transmission and reception operations are performed between the copying machine main body 4 and the reading device 8 according to the data input/output sequence shown in FIG.

In this embodiment, even in the standby mode, when the paper sensor detects that the copy mode designated paper 51 is inserted into the reader 8 from the insertion slot 9, the paper detection signal is output. is transmitted to the copying machine main body 4 side to cancel the standby state, and the conveyance motor 49, reading sensor 50, etc. are operated in the reading device 8 to read the mode information of the copy mode specification paper 51, and the copying machine main body 4
This is used to send the data to the other side and have it set its mode.

Such control is executed using a process according to a flowchart as shown in FIG. 1 as a control means.

Therefore, a more detailed explanation will be given with reference to FIG. When the main switch of the copying machine is turned on to turn on the power, the control circuit shown in FIG. 4 is turned on and the program stored in the ROM 41 is executed. First, a sheet input disable signal is sent to the reading device 8, and the copying machine checks whether there is a sheet input prohibition condition, and then checks whether the copying machine main body 4 side can accept the data on the copy mode specification form 51. . Here, sheet input prohibition conditions include jams, equipment abnormalities, open door covers, etc.
This is a condition that prevents the copy mode from being changed. If there is a sheet input prohibition condition, a sheet input prohibition signal is transmitted and it is constantly checked again whether there is a sheet input prohibition condition.

If there is no sheet input prohibition condition or no longer exists, the insertable indicator 11 lights up to send a sheet input enable signal to the reading device 8), and waits for the copy mode designation sheet 51 to be inserted. When the paper sensor detects that the copy mode designated paper 51 has been inserted, a sheet input presence signal is transmitted from the reading device 8 to the copying machine main body 4.

At this time, check whether it is in standby mode. In the timer OFF mode, which is one of the standby modes, the AC power system loads such as the fusing heater and fan motor are turned off, so these loads are turned on and the operation unit 6 is turned on.
Turn on the display to cancel the timer OFF mode. Furthermore, if the mode is not the timer OFF mode but is in the preheating mode, which is one of the standby modes, the display on the operation unit 6 is turned on to cancel the preheating mode. In the preheating mode, the AC power system loads such as the fixing heater remain on, so there is no need to turn them on again. In any case, even in the standby mode, when the insertion of the copy mode designation sheet 51 is detected, the standby mode is canceled in the same manner as the mode release key operation, and the mode can be set. When not in standby mode, mode settings can be made as usual.

After processing such as canceling the standby mode, the copying machine main body 4 sends a transmission ready signal to the reading device 8, and copies the copy mode specification sheet 5.
Wait for data to be received by 1 read. When all the data on the copy mode designation sheet 51 as shown in Table 1 has been received, the standard copy mode is first set before setting the designated mode. As a result, the standard mode will be set for modes that have not been specifically designated by the copy mode designation sheet 51, and will not be the previously set modes. Thereafter, the designated mode is set according to the mode information transmitted by reading the copy mode designation sheet 51. When the mode setting is completed, the process returns to checking the seat manual power prohibition conditions.

Incidentally, the designation mode setting process is performed according to the flowchart shown in FIG. 7 (this corresponds to the copy mode setting means). First, if there is data in the number of copies designation section 52, the value of that data is set on the number of copies display of the main body 4 of the copying machine. We can't do anything without data. Further, if there is data in the copy size designation section 53, the paper feed table 1, 2, or 3 on which paper of that size is set is searched and set. If there is no paper feed tray that matches the specified size data, a paper feed tray containing paper is selected. Priorities are set for paper feed trays 1, 2.3, and in this example, the order of priority is given to the paper feed trays 1, 2, and 3.
Examine in the order of paper feed tray 3 → first paper feed tray 1 → second paper feed tray 2.

Does nothing if there is no size data. If there is data in the copy magnification specifying section 54, the copy magnification is set. If there is no data, the standard 1x mode will be used. If there is data in the double-sided copy designation section 55, a double-sided copy mode is set; if not, nothing is done. If there is data in the sorter mode designation section 56, the sorter or stack mode is set according to the data, and if there is no designation, nothing is done. If there is data in the program specifying section 57, the memory No. specified by the data is called and set to the mode of the memory contents. Regarding the data in the preliminary designation section 58, if the copying machine is of a model whose mode has been specified in the preliminary designation section 58, the mode is set according to the data.

Effects of the Invention As described above, the present invention is provided with a control means for canceling the standby mode when insertion of a copy mode designated sheet into the reading means is detected during the standby mode of the copying machine main body.
Even if you are in standby mode such as timer OFF mode or preheating mode, if you insert a copy mode specification sheet into the reading means to copy and set the mode, the standby state will be canceled and the read mode information will be wasted. It is possible to copy in a mode set according to the information without having to perform a standby mode release operation using a key.
