Provided is a power system that can arbitrarily set output power while stabilizing output voltages. Connection terminalsandof lower power sourcesandare connected to external connection terminalsin parallel. Voltage measurement sectionmeasures voltage values of external connection terminalsas measured voltage values. Power convertersandmeasure power supply capacities of lower power sourcesand, respectively. Output instruction sectionadjusts power or currents flowing through connection terminalsandbased on the measured voltage values and the power supply capacities so that the measured voltage values are included in a predetermined voltage range.

Power system and control method of the power system

A card system according to the present invention comprises a card connector, which is provided in an electronic device, a wireless communication card, which is inserted removably into the card connector, and an antenna unit, which is provided in the electronic device and connected electrically to the card connector. In the card system, the card connectorcomprises connector-side device terminals, which are connected electrically to the electronic device, and a connector-side antenna terminal, which is connected electrically to the antenna unit. Accordingly, the wireless communication cardcomprises card-side device terminalsand a card-side antenna terminal, which are connected electrically with the connector-side device terminalsand with the connector-side antenna terminal, respectively, when the wireless communication cardis inserted into the card connector

Card system

A connection-retaining unit comprises a connection-retaining body, which includes a through-hole, a plate-like memory card, which is inserted into and extracted from the connection-retaining body, and a flexible printed board, which is also attached to and detached from the connection-retaining body. A plurality of connection terminals are provided in the through-hole, each connection terminal having a print side terminal portion and a memory side terminal portion. The print side terminal portions of the connection terminals are connected with the electrically conductive pathways of the flexible printed board, which are exposed at an end thereof, while the memory side terminal portions are connected with the terminals of the memory card, which are provided at a front end thereof.

Connection-retaining unit

A card connector,comprising a card member,having card-side terminals,on the leading edge thereof, a card holding member,which has mother-apparatus-side terminals on the leading edge thereof and which the card member,can be inserted in and extracted from, and a slider,which slides inside the card holding member,along with the insertion and extraction of the card member,. An oscillating member,which can oscillate freely is provided in the slider,, an engaging protrusion,which engages with the engaging indention on the card member,is formed in the mid section of the oscillating member,, and a cam protrusion,is provided at the tip of the oscillating member,. A cam groove,is provided on the inside side wall of the card holding member,in opposition to the tip of the cam protrusion,. By means of the cam mechanism consisting of the cam protrusion,and the cam grove,, the card member,is held in the card holding member,in the state where the card-side terminals,are in contact with the mother-apparatus-side terminals,as a result of the card member,being pushed into the card holding member,, and the card member,is positioned and held in the position where it can be inserted in and extracted from the card holding member
