Abstract

PURPOSE:To execute current supply to an apparatus body only by one sensor in its loading stage by providing the system with an inserting position detecting means and a means for controlling the start of current supply to an electronic apparatus and temporarily interrupting the current supply to the electronic during the insertion of the apparatus into an external memory. CONSTITUTION:In an unloaded state of a ROM 1, current supply from a power supply 11 to a main board 12 is executed because a relay 13 is ON, but at the time of loading the ROM 1, a lower mark 7B of the ROM 1 is passed through an opposite position to a sensor receiving part 6 at first, an OFF signal is outputted from a signal converter 14 to the relay 13 and the power supply 11 is temporarily interrupted to stop current supply to the main board 12. At the time of completion of setting based upon the succeeding loading operation, an upper mark 7A of the ROM 1 is moved to the opposite position to the sensor receiving part 6, so that an ON signal is outputted again from the signal converter 14 to the relay 13 and current supply to the main board 12 is restarted.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a power supply control system for electronic equipment, and more specifically,
The present invention relates to a power supply control method when replacing an external memory in an electronic device such as a memory pack such as M or RAM or an IC card.

(Prior art) Conventionally, in electronic devices such as home computers, if you replace the ROM back with the power turned on, operation is not guaranteed on both the software and hardware, and in the worst case, the hardware may be damaged. To prevent this, the power must be turned off during the above-mentioned replacement, and the power must be turned on again after the replacement.

However, in the conventionally proposed energization control method, two sensors are provided on the main body of the electronic device, and when an external memory device is used, the first sensor first detects that it is being installed. The device was configured so that the power was turned off, and then the power was turned on again when the second sensor detected that the attachment was completed.

[Problems to be Solved by the Invention] In view of the above-mentioned points, an object of the present invention is to simply equip an electronic device with one sensor, and use this one sensor to control the power supply according to the external memory replacement operation. An object of the present invention is to provide an inexpensive energization control method for electronic equipment in which power is cut off and turned on again.

[Means for solving problems]

In order to achieve such an object, the present invention provides a power supply control method for an electronic device when an external memory is inserted into a slot for inserting an external memory. and a second detected object, and the electronic device includes an insertion position detection means capable of detecting the first and second detected objects during and during insertion of the external memory, and an insertion position detecting means in the slot of the electronic device. means for controlling such that when the first detected object is detected by the position detecting means, power supply to the electronic device is cut off, and when the second detected object is detected, power supply to the electronic device is started; The present invention is characterized in that power to the electronic device is temporarily cut off while the external memory is being inserted. - [Function] In the energization control method for electronic equipment of the present invention, in the process of inserting or pulling out an external memory into a slot of an electronic equipment such as a computer, two different objects to be detected, which are externally packaged in the external memory, are placed in the slot. The signals are detected one after another by a single signal detection means, and the corresponding detection signals turn off the power to the main unit of the device, for example, once it is plugged in.
After being turned off, it is turned "on" again when the installation is complete, and when it is removed, it is turned "off" in the middle of removal, and then turned "on" again after removal is completed.

〔Example〕

Embodiments of the present invention will be described in detail and specifically below based on the drawings.

FIG. 1 shows an embodiment of a ROM mounting part to which the present invention is applied, where 1 is a ROM back of an external memory (hereinafter simply referred to as ROM), and 2 is a ROM back on the computer equipment main body side.
The board on which the MI is mounted, 3 is a socket for mounting the MI on the board 2, and in this example, the ROM 1 is mounted toward the socket 3 from the position shown in the figure. Reference numeral 4 denotes a sensor mounting member protruding from the board 2 in the mounting direction of the ROMI, and an optical sensor transmitting section 5 and an optical sensor receiving section 6 are sequentially arranged on this mounting member 4 from above as shown in the figure. On the other hand, the ROM 1 is provided with an upper mark 7A and a lower mark 7B correspondingly above and below.

In such a configuration, when the ROM pack 1 is installed in the socket 3 from the position shown in the figure, when the ROM pack 1 is moved 8 times along the upper and lower installation path, the lower mark 7B will first be attached to the sensor receiving section. Pass through the direction position of 6,
Next, when the upper mark 7^ comes down to a position opposite the sensor receiving section 6, the installation of the ROM 1 into the socket 3 is completed.

FIG. 2 shows an example of a circuit for controlling power on/off during the loading process of the ROM 1 using a set of sensors constituted by the transmitter 5 and the receiver 6 as described above. Here, 1 is a power supply for supplying power to the main board 12 of the computer equipment, 13 is a relay disposed in the middle,
14, relay 1 is activated by the received signal from sensor receiver 6.
3 is a signal conversion device that outputs an on/off signal; 15 is a signal line thereof; and 16 is a wiring for power supply. In the signal conversion device 14, as shown in FIG. 3, when neither of the marks 7A and 7B is detected, that is, in the state shown in FIG. 1, the relay 13 is turned on. It also provides an output signal for the bottom mark 7.
When the upper mark 7A is in the opposite position, an "off" output signal is supplied to the relay 13, and when the upper mark 7A is in the opposite position, an "on" output signal is supplied to the relay 13.

Therefore, the beam relay 13 was installed without ROM 1 installed.
Since the main board 12 is “on”, power is being supplied from the power supply 11 to the main board 12, but when installing the ROMI,
When the lower mark 7B of the ROM 1 first passes the opposite position of the sensor receiving section 6, an "off" signal is output from the signal converter 14 to the relay 13, the power supply 11 is temporarily cut off, and the main board 12 is no longer energized. will be stopped. However, when the setting is completed by the subsequent mounting operation after the lever, the upper mark 7^ of the ROM 1 is in a position opposite to the sensor receiving section 6, so that the detection signal from the mark 78 causes the signal converter 14 to transfer to the relay 13. “
"ON" signal is output, and power supply to the main board 12 is restarted.

Also, when pulling out the ROMI from socket 3,
The above-mentioned procedure is reversed, and the power supply to the main board 12 is temporarily stopped during the operation, and the power supply is restored again when the main board 12 is completely pulled out.

In the above embodiment, an optical sensor is used as the sensor, and the output signal from the signal converter differs depending on whether or not light is detected depending on the shape of the mark. In addition, in the above example, the electricity from the power supply was turned on and off by a relay, but instead of the relay,
It goes without saying that a switching element such as a diode switch or a thyristor may be used.

Furthermore, the power supply control method of the present invention is of course applicable to computer equipment, not only home computers, etc., but also various electronic equipment that can be equipped with external memories that require replacement, such as ROMs and IC cards. It is.

Incidentally, in the case of a ROM or the like, the above-mentioned mark can be used as a means for the user to confirm whether or not the front and back orientation is correct when the ROM is installed.

(Effects of the Invention) As described above, according to the present invention, it is possible to energize the main body of the device with one sensor during the installation process, and to mount an external memory while the device is being energized. Therefore, it is possible to provide an inexpensive energization control method for electronic equipment.
