A battery pack includes a switching element, a heat resistor, and a fuse. The switching element turns to ON if the battery pack becomes in an abnormal state. The heat resistor is connected to the switching element and a battery in series. Current flows through the heat resistor when the switching element turns to ON. The fuse is located in a position where the fuse is heated by the heat resistor through which the current flows. The fuse is connected to the battery in series so that the fuse is disconnected with heat by the heat resistor at high temperature. Thus, the fuse cuts off a current flow in the battery. If the battery pack is in an abnormal state, when the capacity or voltage of the battery is less than a preset capacity or voltage value, the fuse is disconnected with heat by turning the switching element to ON.

An image forming apparatus of the present invention is an image forming apparatus into which a memory device is insertable and which performs a printing process on an image of image data stored in the memory device. The image forming apparatus includes a memory reading section for detecting insertion of the memory device into the image forming apparatus, and a display processing section for performing a notification process of warning of accidental ingestion of the memory device, when the memory reading section detects the insertion of the memory device. This makes it more surely possible to cause a user to give attention to accidental ingestion by young children.

A method controls a battery pack that includes a rechargeable battery, a control circuit that controls charge operation of the battery, and a charge control element that controls the charge current through the control circuit. In the method, even though the control circuit controls the charge control element so that the charge control element turns to OFF, in a case where the charge current is detected, the control circuit determines that abnormality occurs if detecting that the current flows at a rate not less than a first current value during a first detection period, and additionally determines that abnormality occurs if detecting a state the current flows at a rate less than the first current value for a second detection period longer than the first detection period.

One cycle is corrected every charging/discharging cycle in accordance with a cycle deterioration accelerating coefficient. The corrected one cycles are accumulated. A storage period is corrected in accordance with a storage deterioration accelerating coefficient every hour. The corrected storage periods are accumulated. In the storage period, a rechargeable battery is stored with the terminal voltage higher than a predetermined voltage. A deterioration coefficient is obtained as the product of a cycle deterioration coefficient calculated in accordance with the accumulated cycle number, and a storage deterioration coefficient calculated in accordance with the accumulated value of the storage periods (Step S42). If the deterioration coefficients falls within the range 0.3 to 0.7 (Step S43, 44: NO), the setting voltage in constant-voltage and constant-current charging operation is decreased from 4.2 to 4.1 V (S45). If it is smaller than 0.3 (S43: NO, S44: YES), the setting voltage is decreased to 3.8 V (S46).

Providing an optical transceiver module that reduces electric crosstalk between a light emitting device and a photodetector while providing an excellent high-frequency characteristic, and an optical transceiver including the same. According to the invention, a first metal plate having a first substrate for mounting a light emitting device and a at second metal plate having a second substrate for mounting a photodetector are provided separately and independently of each other in a resin package, thus reducing the parasitic capacitance. This provides an optical transceiver module capable of suppressing electric crosstalk where part of a high-frequency signal causes a variation in the potential at a terminal of a photodetector while improving the high frequency characteristic in driving the light emitting device with a high-frequency signal, and an optical transceiver including the same.
