Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention analyzes the usage status of a copying device, such as the number of copies, by department or group within an organization such as a company, based on a registered code number. The present invention relates to a copying apparatus equipped with a management function.

[Conventional technology]

Conventionally, in large-scale copying machines, in order to manage usage status such as the number of copies by department or group within an organization, a code number is registered for each department and stored on a personal card. Alternatively, if the node number entered using the numeric keys matches the one registered in advance, copying is permitted, and a counter in the recording device manages the number of copies allowed for each department. things are provided.

[Problems that the invention aims to solve]

By the way, in general, within an organization such as a company, there is an extremely large amount of information that needs to be communicated, such as schedules, and most of this information needs to be communicated only to personnel belonging to specific departments. It has been difficult to reliably transmit such information. A control means for managing the usage status of the copying machine for each code number, a message input means for inputting a message, a message storage means for storing the input message, and a message storage means for inputting a predetermined code number. Message display means for displaying messages stored in the memory.

[For production]

According to the above configuration, if you want to send a message to a person in a predetermined department within an organization, you input the message into the copying device and also specify the code number that corresponds to the department to which the person to whom the message should be sent belongs. If this is done, the message will be displayed when personnel in that department use the copying machine, making it possible to transmit information within the organization through the copying machine.

FIG. 6 shows the liquid crystal display device 46 in a standby state. In this standby state, input of a code number is awaited. When a code number set for a predetermined group or department within an organization such as a company is input using the numeric keypad 55 consisting of 10 numeric keys from "O" to "9", the code number is displayed on the numeric display section. 56. The numeric keypad 55 is normally used to set the number of copies, and the numerical display section 56 is normally used to display the number of copies.

When a code number is input, it is determined whether it is a pre-registered number or not. If the input code number is registered, the screen switches to the basic screen shown in Figure 3. The print switch 57 is then turned on, making it possible to make copies. In this copyable state, it is possible to switch among the various modes described above and to set copy density, copy magnification, and the like.

FIG. 7 shows the control section of the copying machine.

The operation panel 45 is connected to a CPU (central control unit) 59 as a control means via an interface circuit 58. CPU59 is ROM (Read Only
Based on the processing program stored in the memory) 60, each display area 46a to 46i of the liquid crystal display device 46 of the operation panel 45 is controlled in response to signals input by various keys on the operation panel 45, and the interface circuit Each part within the copying apparatus main body 1 and the copying apparatus holding stand 25 is controlled via the copying apparatus 61.

Additionally, a RAM (Random Acc) which is connected to the CPU 59 and also serves as a message storage
essMemory) 62 is a memory for storing the code number set corresponding to each department, the allowable number of copies assigned to each department, the number of copies already made, and a message to be transmitted to the personnel of a predetermined department. A removable data memory area is provided. Code number above,
The number of copies, etc. will be called up and processed by the CPU 59 as necessary.

Next, the control procedure by the CPU 59 will be explained based on the flowchart of FIG.

First, when the power of the copying apparatus main body 1 is turned on (Sl),
The control unit and the copying apparatus main body 1 are initialized (S2),
Warm-up is started (S3). Subsequently, it is determined whether or not the warm-up has been completed (S4), and when the warm-up is completed, the system waits for input of a code number as shown in FIG. 6 (S5).

Next, it is determined whether the input of the code number using the numeric keypad 55 has been completed (S6), and if the input of the code number has been completed, then the code number stored in the RAM 62 is checked (S7). ), it is determined whether the code number that has been sawn is already registered (S8). If the entered code number is not registered, a warning display (S
After step 9) is performed, wait for the code number to be input again (S5).
).

On the other hand, if the input code number is registered, it is then determined whether or not a message is stored in the RAM 62 for the personnel of the department to which the code number is set (SIO), and the message is stored. If so, the message is displayed on the display area 46h of the liquid crystal display device 46 for a predetermined period of time (S11), and then the screen is switched to the basic screen as shown in FIG. 3 (S12). On the other hand, if no message is stored, the screen is immediately switched to the basic screen shown in FIG. In this state, it is possible to switch various modes and set the copy magnification, copy density, etc. (S
13).

Thereafter, it is determined whether the print switch 57 is turned on (S14), and if the print switch 57 is turned on, the copying process is started (S15). When the copying process is completed, the data in the RAM 62, such as the number of copies that have been made, is updated, and then the system returns to a state of waiting for input of a code number (s5).

Hereinafter, a message setting procedure will be explained when it is desired to transmit a message to personnel in a predetermined department within an organization using the listening device.

When inputting a message, first operate the special function key 63 on the operation panel 45 to enter the message setting mode. In this message setting mode, keys 51 to
The key 53 is given the role of a non-sage input means, and the key 51 is used as a return key. That is, each time the key 51 is operated, for example, "ka" - "
50 characters are displayed in the mesosage display area 46h of the operation panel 45, such as "O"-"E"-→"U"-°Ipa→'A".
The next hiragana in phonetic order is displayed sequentially.

On the other hand, the key 52 is used as a gift key, and the key 52
When you operate , for example, "A" - "I" - Geu 3 - ◆ "E" - "O" → "Ka", etc., in the message display area 46h, in alphabetical order. The next hiragana is displayed sequentially.

Also, the key 53 is used as a setting key in this case,
When the desired hiragana is displayed in the message display area 46h, when the key 53 is operated, that hiragana is stored in the RAM 62, and then the cursor is shifted so that the next hiragana can be input. There is. The key 53 also has the role of a shift key, and when the key 53 is pressed blankly, the
A space is stored in AM62 and the cursor is shifted. The capacity of one message is set to, for example, about 16 characters, and it is considered that the message input is completed when a predetermined number of characters have been input. Note that if the actual message does not have the predetermined number of characters, it is sufficient to input spaces corresponding to the missing number of characters.

Once the input of the message is completed, the system enters an input mode for inputting the code number corresponding to the department to which the person to whom the message is to be transmitted belongs. In this state,
When a code number is input using the numeric keypad 55, the code number is stored in the RAM 62 along with the message, and when the person in the department assigned the code number inputs the code number at the time of copying, the message is displayed on the liquid crystal display 46. It will be displayed in the message display area 46h.

Here, for example, if you want to input the message "Gaigi 14 Jigara" for the personnel in the department assigned the code number "34567°", switch to the message setting mode and operate the key 52 as the send key. This calls up “ka” and then presses key 53 as a setting key.
Enter "ka" by operating .

Hereafter, in the same way, “i”, “ki”, “”, 1″, 4″
, 'shi', 4', 'ka', 'ra', and if the capacity of one message is 16 characters, you can input the message by entering the spaces for the missing 6 characters. This is completed. Thereafter, by inputting the code number 34567'' using the numeric keypad 55 and operating the key 53 as a setting key, the message input is completed.

Note that the message may be displayed not only before copying but also during the copying process. In addition to entering the code number using the numeric keypad 55, it is also possible to enter the code number by inserting a personal card, for example.

Next, a modified example will be described.

In this modified embodiment, when the copying apparatus manages the number of permissible copies by code number, in other words, by department within an organization such as a company, when the remaining number of copies that can be made is low, a message to that effect is displayed on the LCD. Message display area 46 of display device 46
It is automatically displayed on h.

The details of the control procedure by the CPU 59 in this case are as shown in the flowchart of FIG. 8. First, a code number and the allowable number of copies and number of copies that have been made corresponding to the code number are read from the RAM 62 (Sl). Next, the remaining number of copies that can be made is calculated based on the allowable number of copies and the number of copies that have been made, and it is determined whether the remaining number of copies that can be made is less than or equal to a predetermined number (S2).

If the remaining number of copies that can be made is less than the predetermined number, the code number and a message that the remaining number of copies that can be made are low will be sent to the RA.
The information is stored in M62 (S3), thereby completing preparations for displaying a message indicating that the number of remaining copies that can be made is small when a person in the department to which the code number is assigned makes copies.

Thereafter, it is determined whether or not another code number is stored in the RAM 62 (S4). If another code number is stored, the process returns to Sl and repeats the same process as described above. Further, if no other code number is stored in the RAM 62 in S4, the remaining number confirmation process is ended. If the remaining number of copies that can be copied is greater than the predetermined number in S2, it is immediately determined whether another code number is stored in the RAM 62 (S4), and the same processing as described above is performed.

〔Effect of the invention〕

As described above, the copying apparatus according to the present invention includes a control means for managing the usage status of the copying apparatus for each registered code number, a message input means for inputting a message, and a message storage for storing the input message. and message display means for displaying a message stored in the message storage means when a predetermined code number is input.

With this, if you want to send a message to people in a specific department within your organization, you can enter the message into the copying device and specify the code number that corresponds to the department to which the person to whom the message should be sent belongs. Since the message is displayed when the person using the copying machine, it is possible to transmit information within the organization through the copying machine.
