Abstract

PURPOSE:To reduce the number of parts to reduce the cost by performing register, clear, stop, and reset operations in the copying operation with one key. CONSTITUTION:The signal inputted by a copy key 2 is inputted to a sequence controller 3 through a resistance R, and required control is performed to drive a load 4. A LED is used to see the operation state of the copy key 2. That is, counting, copy start, or stop is decided to operate a copying machine by the control based on the input time of the key as shown by a timing chart of read of the sequence controller 3 due to turning-on/off time of the copy key 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying machine equipped with an operating device that operates copying operations other than density setting with a single key.

[Conventional technology]

Conventionally, the operation section 11 of a copying machine has the following functions, as shown in FIG.
Copy key 2. Stop key 12. Place number key 13. Number clear key 14. Various keys such as a concentration lever 15 and a number display 16 are provided.

[Problem that the invention seeks to solve]

However, having such a large number of operation keys makes operations cumbersome for the user and difficult to handle.In addition, from a cost perspective, the large number of parts not only increases the cost. However, there are problems in that the number of failures increases and the reliability decreases.

Furthermore, with the recent progress in miniaturization, the actual situation is that it is difficult to obtain a large amount of space for the operation section, resulting in an unreasonable equipment configuration, and some kind of simplification is desired.

[Means for solving problems]

In view of the above-mentioned circumstances, the present invention has a configuration in which copying operations other than density setting are operated with one key, and the ON1
These problems can be resolved by determining the operation based on the 0 F F time, and stopping or resetting it when there is no key input for a certain period of time after the key is turned on, or by turning the key on during copying. It aims to solve the problem.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 8.

FIG. 1 is a schematic plan view showing the main parts of the copying machine of this embodiment, and the operation section 1 is only provided with a copy key 2 and a density key 15. As shown in FIG.

FIG. 2 is a basic configuration diagram of this embodiment. copy key 2
The input signal enters the sequence controller 3 through the resistor R, performs necessary control, and drives the load 4. Note that the LED 5 is for viewing the operating state of the copy key 2.

FIG. 3 shows a modified example, in which the input of the copy key 2 is configured so that an accurate one pulse is input to the sequence controller 3 through the one-shot multivibrator 6. It is possible to prevent such things. The input from the resistor R is related to the input to start copying if the copy key 2 is kept ON for a certain period of time, which will be explained in the flowchart described later.

Further, the buzzer 7 sounds the count inputted by the copy key 2 in synchronization with the key 2, and informs the user how many times the count has been inputted. However, even if the buzzer is not 7,
Needless to say, EDS may also be used.

What is shown in FIG. 4 is the input by the copy key 2,
This is an example in which a clear key 10 is provided separately for stopping the copying operation and clearing the set number. The display LED 9 is displayed by the driver 8, and if a necessary number of LEDs 9 are provided, the number of inputs is stored in memory.

Next, the present invention will be explained in detail with reference to flowcharts shown in FIGS. 5 to 7. Here, 81 to 814 indicate each step of the flowchart.

First, FIG. 5 will be described.

Copy key 2 is turned on while the copier is on standby (S
l), and in S2, this ON time is set to a predetermined time t, (s
) or less is determined, and if it is less than or equal to (
S3) is displayed (S4).

Similarly, if a signal less than (s) is input at time t, the count is increased by that amount. In other words, this is the input of the numeric value.

Next, the count input disappears and a predetermined time t2 (S)
If there is no input above, it is assumed that copying is not necessary.S5), S
Clear the count at 10 and return to standby. But time t! If the copy key 2 is turned ON within (S) (SS), counting or copying will be started. That is, in the next step S6, the time t I (
S) Above, with copy key 2 still turned on,
The copy starts (S7).

From now on, if you want to stop halfway, turn on copy key 2 during copying (S8) and the copying will stop (S9
). However, if the number count reaches "1" without turning on copy key 2 (S11), copying will stop automatically (
S9).

That is, by control based on the input time of only one key, as shown in the timing chart of reading by the sequence controller 3 based on the ON/OFF time of the copy key 2 in FIG. This means that it is possible to determine whether the device is running or stopped and then operate it.

The following chart 70 in FIGS. 6 and 7 is an example in which the clear key 10 shown in FIG. 4 is provided. Any position on the flowchart is acceptable, but as shown in Figure 6,
If the operation is to be performed after the display of 4 is turned ON, when the clear key 10 is turned on (812), the count must be reset (5IO), and the operation is to be performed after the copy start of 87 as shown in Fig. 7. If (
813), stop the copying (S9), and if the number reaches "1" even if it is not pressed (S14), stop the copying (S9).
9). That is, this clear key 10 plays the same role as the clear key 14 of the conventional machine.

Although not described in chart 7a, if the copy key 2 is held down, the next operation will proceed, as in the case of the conventional machine.

〔Effect of the invention〕

As explained above, the present invention has a configuration in which the operation section only includes the copy key and the density lever, which not only occupies a small space and is advantageous for downsizing, but also reduces costs by reducing the number of parts. This has the effect of improving reliability as the number of failures decreases.

It also has the advantage that the simplification of the operation keys makes it easier for the user to operate.
